Vietnamese steel mill Hoa Phat Group announced that its subsidiary Hoa Phat Dung Quat Steel, together with its partner Horus Power, has begun construction of the third phase of the rooftop solar power project, increasing installed capacity by 26.8 MW.
Once operational, the third phase is expected to generate approximately 42.8 million kWh of renewable electricity in year and reduce carbon dioxide emissions by almost 28,200 tons per year.
The new stage supports decarbonization and energy efficiency
The new stage will increase the share of renewable energy used in the company's integrated metallurgical complex, gradually reduce carbon dioxide emissions, optimize energy costs and improve production efficiency. The project also supports the company's long-term development strategy, compliance with ESG standards and compliance with the global energy transition.
Hoa Phat Dung Quat Steel began investing in the rooftop solar project in 2025 with a total investment of VND 600 billion. The project has a planned total capacity of 79.2 MW and aims to increase the company's self-sufficiency in renewable electricity, reduce operating costs, reduce emissions and improve environmental performance. According to the company, this is one of the largest rooftop solar projects in Vietnam's industrial sector.
The full project is scheduled to be completed in the second quarter of 2027.
The project consists of five phases. Phases 1 and 2 were installed in November 2025 and March 2026, with completion of the entire project scheduled for the second quarter of 2027.
Once completed, the project is expected to generate more than 115 million kWh of clean electricity annually and reduce carbon dioxide emissions by more than 78,000 tons per year.
The company said it is expanding its use of renewable energy. The use of renewable energy is becoming an increasingly important strategy for steelmakers seeking to improve competitiveness and meet increasingly stringent environmental regulations in both domestic and international markets.
